Harmonic pulsation / Vibration?????????

motor mounts... When I had my golf car shop, I had 2 main parts suppliers for a certain motor mount. They both looked identical but, one had a lot harder rubber, the thing would shake and vibrate something fierce... other vendor's mounts, no issues. After a couple golf cars like that, I only bought mounts from the one vendor! I"d go get a pair of regular black motor rubber mounts and try that.

Thanks, Will put that on my list to try
